Somebody knows how to ignore capitalization with regular expression in Notepad++?

From shell it works as follows:

egrep -i '^(FroM|SuBjeCT|DatE): ' filename.txt

Thanks in advance.

In the Find dialog use the Match case checkbox to choose whether you want case-insensitive searching or not, ie. leave it UNCHECKED to ignore capitalization with NotePad++ regular expressions.


You can use the ?i modifier.
